School desegregation: income vs. race

Struggling to improve schools that have large populations of poor and minority students and under legal pressure to avoid racial busing, a small but growing group of school districts are integrating schools by income.

More than 60 school systems now use socioeconomic status as a factor in school assignments, says Richard Kahlenberg, a senior fellow at the Century Foundation, which studies income inequality. Students in Champaign, Ill.; Kalamazoo, Mich.; and Louisville have returned this year to income-based assignments.
